NN4 + EZ-Leveler for multirow mostly
I'm planning to buy NN4 with RD16 for shooting multirow panos mostly: landscapes, buildings exteriors, skylines. Spherical panoramas is an option, but not the goal.
My gear is Canon 5d MKII, Canon 16-35mm II, Sigma 50mm, Canon 90mm TS-E, Canon 70-200mm f4 IS (I know about 100mm limit but I'm going to shoot on 70-100mm focal length)
My questions are:
1. Do I need to buy EZ-leveler if I'm not going to shoot 360 panos, will it be useful for my goals?
2. Is it possible to use 70-200 lens for single row panos, will be the Lower Rail length enough for this lens? According to Entrance Pupil Database L2 for Canon EF 70-200 f/4.0 @70mm is 92mm,
then L1+L2 is 130,5mm and will not be supported by NN4? Does it mean that it's impossible to use this lens with NN4 or my calculations are wrong?
